python - pytz and astimezone() cannot be applied to a naive datetime -
i have date , need make time zone aware.
local_tz = timezone('asia/tokyo') start_date = '2012-09-27' start_date = datetime.strptime(start_date, "%y-%m-%d") start_date = start_date.astimezone(local_tz) now_utc = datetime.now(timezone('utc')) local_now = now_utc.astimezone(local_tz)
i need find if true:
print start_date>local_now
but error.
start_date = start_date.astimezone(local_tz) valueerror: astimezone() cannot applied naive datetime
i convert utc tokyo no issue. need make start_date timezone aware ad in tokyo.
thanks
for pytz
timezones, use .localize()
method turn naive datetime
object 1 timezone:
start_date = local_tz.localize(start_date)
for timezones without dst transition, .replace()
method attach timezone naive datetime
object should work:
start_date = start_date.replace(tzinfo=local_tz)
see localized times , date arithmetic of pytz documentation more details.
